Legionella Risk

Legionella is a risk for almost all water systems found within buildings and must be effectively controlled in accordance with ACOP L8 under the Health and Safety at Work Act. If you manage any water system within a building you need to have a risk assessment along with reasonable control measures in place. H20 Water Solutions can help you achieve this.

Health & Safety

General duties for health and safety are imposed under the HSW Act 1974, whereby you have to consider the risks from Legionella that may affect your staff or members of the public and take suitable precautions. Further supporting these general duties the employer also has to consider those requirements defined within the COSHH 2002 regulations relating to the risks from hazardous micro-organisms including Legionella, and also to risks from chemicals such as biocides and chlorine used for the treatment of Legionella. It should be noted that the HSC, (which incidentally merged with the Health and Safety Executive in April 2008) introduced the L8 Approved Code Of Practice entitled 'Legionnaires' disease : The control of Legionella bacteria in water systems'. The ACOP gives practical advice on meeting both the requirements of the COSHH 2002 and the Management of Health and Safety at Work 1999 regulations. Penalties for non compliance to the L8 ACOP can be severe, and considering the potential risks from Legionella,it is probably not surprising that fines can reach five figures and possible criminal charges (probably laid under s.3 of the HSW Act 1974).

Legionnaire's disease is a potentially fatal form of pneumonia. The bacteria reproduce to high numbers in warm, stagnant water (between 20°C and 50°C). Humidifiers, plumbing systems and hot & cold water storage, tanks, spa baths, pools, water softeners, showers, car washes, fire and sprinkler systems, air conditioning systems, cooling towers and many other systems using water and operating at temperatures in excess of 20°C can generate an aerosol presenting a legionella risk. High temperatures of 60°C and over will kill the bacteria.
